3. In the expansion of (ax^2+ by)^8 the coefficients of last two terms are -5832 and 6561, respectively.
Find the values of: a and b
Answer:
a = -0.33
b = 3
Step-by-step explanation:
(ax²+ by)⁸
by the 8th level of Pascal Triangle, the coefficient of last 2 terms are
8 a*b⁷ = -5832 ... last 2nd term 8 ab⁷ x²y⁷
b⁸ = 6561 ... last term b⁸y⁸
b = 3
a = -5832/(8*3⁷) = -0.33
A rock has a mass of 126 grams and a density
of 1.8 grams/cm.
Work out the volume of the rock.
Answer: 70 grams^3
Step-by-step explanation: volume = mass/density volume = 126/1.8 volume = 70 grams^3
The value of the volume of the rock will be;
⇒ Volume = 70 cm³
What is Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The mass of rock = 126 grams
The density of rock = 1.8 grams/cm
Now,
Since, We know that;
⇒ Volume = Mass / Density
Here, The mass of rock = 126 grams
The density of rock = 1.8 grams/cm³
Substitute all the values we get;
⇒ Volume = Mass / Density
⇒ Volume = 126 / 1.8
⇒ Volume = 70 cm³
Thus, The value of the volume of the rock will be;
⇒ Volume = 70 cm³

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Kyle Lowry earned $31.2 million.
So, In each month he read
= 31200000 / 12
= $2,600,000
and, in each day she earn
= 2, 600, 000 / 30
=86,666.666
and, in each hour she earn
= 2, 600, 000 / 24
= 3611
Hence, He was earning 3562 each hour.

Which equation represents this statement?
5 times the sum of 7 and a number is 40.
5(n+7)=40
5 + 7n = 40
5⋅7+n=40
5n + 7 = 40
Answer:
5(n+7)=40
Step-by-step explanation:
It's 5(n+7)=40 because 5 + 7n = 40 and 5n + 7 = 40 is addition not multiplication, and 5⋅7+n=40 is saying 5 times seven plus a number is 40, therefore 5(n+7)=40 is the correct answer because the parenthesis in (n+7) seperates it from 5 so that you have to get the sum of (n+7) before you can multiply it by 5.
The required equation for the given case is 5(n + 7) = 40.
What is a Linear equation?A linear equation is a equation that has degree as one.
To find the solution of n unknown quantities n number of equations with n number of variables are required.
The given word problem can be solved as follows,
Suppose the unknown number be n.
Then, 5 times the sum of the number and 7 can be written as an expression as,
5(n + 7)
Now, as per the question the following equation can be written,
5(n + 7) = 40
Hence, the equation for the given word problem is 5(n + 7) = 40.

A rock is dropped into a pond. What is the spread of the circular ripple after 25 seconds if the ripple travels outward at a speed of 20cm/sec?
Answer:
Since we are assuming a constant velocity, we know that v = d/t which means we can rearrange this formula to solve for distance:
d = v * t
d = (20 cm/sec) * (25 sec) = 500 cm

It takes Max three hours to run 30 kilometers. Georges, on the other hand, travels the same distance in 2 hours and 20 minutes. If both are to complete a 15-kilometre race, how long before Max will Georges arrive to the finish line?
George will arrive 20 minutes before Max
It takes Max 3 hours(180 minutes) to run 30 km .
The rate can be calculated as follows:
rate = 30 / 180 = 1/6 km/ min
George uses 2 hours 20 minutes(140 minutes) to run 30 km.
The rate can be calculated as follows:
rate = 30 / 140 = 3/14 km / min
If both are to complete a 15-kilometre race, Therefore,
Max time will be
1 / 6 = 15 / t
t = 15 × 6
t = 90 minutes
George time will be
3/14 = 15 / t
3t = 210
t = 210 / 3
t = 70 minutes
Time difference = 90 - 70 = 20 minutes
Therefore, George will arrive 20 minutes earlier than Max
